Maximum surrounding air temperature
- operation: +5°C to +50°C (from 40°C, the rated power
must be reduced by 3 % per additional °C)
- storage: -20°C to +70°C.
*
For special applications, the input voltage range can be extended to 230 Vac - 480 Vac (see chapter 2.4 for
reducing the undervoltage threshold to 100 Vdc).
